Monty Resource Definition Drilling
Since the last Monty exploration update ( see Talisman ASX Announcement – 20 January 2016 Monty Exploration Update ), Talisman understands drilling has focused on resource definition within the Upper and Lower Zones of Monty and that this drilling program is essentially complete.
The information generated by this resource definition drilling will support the maiden Mineral Resource estimate for Monty, which Talisman understands to be on track to be completed by the end of March / early April 2016.
The collar locations of holes drilled to date by Sandfire at Monty, for which assay results have been received by Talisman, are shown in Talisman’s interpreted plan view diagram ( see Figure 1 on the following page) .

Figure 1: Plan view of Monty showing Talisman’s simplified stylised geological interpretation and mineralisation overlaid by drill-hole collar locations of holes drilled to date for which assay results have been received by Talisman. Drill hole collars labelled are newly reported holes. For detailed drill hole information refer to Table 1.
Monty - Lower Massive Sulphide Zone
Resource definition drilling has progressed at Monty, focused on the definition of the Monty Lower Zone mineralisation and has been aimed at defining the edge and continuity of the mineralisation via an infill program. Latest significant results received by Talisman are:
TLDD0048 6.6 metres @ 6.0% Cu and 2.2g/t Au from 371.6m – 378.2m (downhole width, top of intercept is 326m vertically below surface); and 7.8 metres @ 11.0% Cu and 2.5g/t Au from 393.0m – 400.8m (downhole width, top of intercept is 344m vertically below surface). TLDD0063 0.8 metres @ 15.1% Cu and 0.7g/t Au from 440.6m – 441.4m (down-hole width, top of intercept is 385m vertically below surface). TLDD0065 5.0 metres @ 4.2% Cu and 0.7g/t Au from 425.6m – 430.6m (downhole width, top of intercept is 358m vertically below surface).

Monty - Upper Massive Sulphide Zone
Drilling of the Monty Upper Zone mineralisation was planned to infill the existing drilling, plus test the potential for extensions to the known mineralisation, both to the north-east and south-west, along strike.
Latest significant results received by Talisman include:
TLDD0056 3.5 metres @ 4.4% Cu and 1.1g/t Au from 186.6m – 190.1m (downhole width, top of intercept is 162m vertically below surface)
TLDD0057 7.6 metres @ 3.3% Cu and 1.5g/t Au from 152.0m – 159.6m (downhole width, top of intercept is 133m vertically below surface)
Further information is required to understand the context of these latest intercepts and the relationship with the existing interpretation for the Upper Zone mineralisation.
However, Talisman considers these latest drill results to be encouraging as they potentially extend the Upper Zone to the north east.
Monty Deeps
In addition to the resource definition drilling, Talisman has been advised that drill hole (TLDD0051) encountered mineralisation in two intercepts which Talisman interprets as being below the currently interpreted extent of the Monty Lower Zone:
TLDD0051 1.5 metres @ 4.7% Cu and 1.8g/t Au from 518.6m – 520.1m (down-hole width, top of intercept is 441m vertically below surface); and
7.6 metres @ 3.2% Cu and 0.2g/t Au from 547.2m – 554.8m (down-hole width, top of intercept is 462m vertically below surface.
The first intercept is located approximately 80m vertically below the currently interpreted extent of the Monty Lower Zone.
Whilst it is too early to draw conclusions as to the relationship between these intercepts and either the Monty Lower Zone or the potential for them to be associated with Monty Deeps, Talisman is encouraged by the result of this exploration drilling and other previously reported intercepts in this area.
Further drilling information and results are required to be received by Talisman in order to better understand the context of all of these intercepts and the relationship with the existing interpretation for the mineralisation at Monty.

Figure 2: Vertical Longitudinal Projection and simplified interpretation, by Talisman, of the Monty discovery with drill-hole pierce points at the top of the interpreted primary intercept. All intercepts are shown as down-hole widths.
New intersections (not previously reported) are shown with white labels and larger dots on the Vertical Longitudinal Projection. Refer to Table 1 and Table 2 for previously released results and new intersections.
A Significant Intersection is defined as any intersection ≥ 3m estimated true width that has a grade of ≥ 2.0 % Cu, inclusive of non-mineralised material. Intersections that are <3m estimated true width are defined as significant if the overall grade remained >2.0% Cu when non-mineralised material has been included at a grade of 0.0% Cu (weighted by width) until a 3m estimated true width is reached.
Other Regional Exploration Activity
As noted in Talisman’s prior releases, in addition to the resource drilling of the Monty mineralisation, joint venture exploration activities are planned to continue at the Springfield Project.
Planned joint venture exploration activities advised to Talisman include:
-
RC drilling to the north east of Monty along the prospective Monty Trend ;
-
RC drilling of geochemical anomalies at Monty South and the Southern Volcanics ;
-
First pass drilling and assessment of the newly identified Monty Deeps ;
-
Continued exploration along the Homer Corridor , including DHEM of TLDD0068; and
-
Infill aircore drilling at Monty South and first pass aircore drilling of a potential structural exploration target in the north east of the Springfield Project.
Priority has been given, by Sandfire, to the completion of Monty resource definition drilling over the past months.

Consequently, the timing of the abovementioned planned exploration activities at Springfield is dependent on the amount, availability and allocation of the drilling resources employed by Sandfire on behalf of the Joint Venture.
Farm-in / Joint Venture Agreement
As announced in Talisman’s ASX release on December 17 2015, Sandfire has reached the $15 million expenditure threshold and an unincorporated Joint Venture has been formed between Talisman and Sandfire.
Formal transfer of Sandfire's initial 51% interest in the Joint Venture was completed in December 2015.
Formal transfer of Sandfire’s final 19% interest in the Joint Venture has now been completed following the satisfactory audit of the further $5 million of sole funded exploration expenditure by Sandfire at Talisman’s Doolgunna Projects.
Talisman is continuing discussions with Sandfire to agree and finalise the terms of an Exploration Joint Venture Agreement under which it will hold a 30 per cent contributing interest in the Doolgunna projects (including the Springfield Project) with Sandfire holding a 70 per cent interest and managing the Joint Venture.

Table 2 : Drill-hole Assay Intersections >1% copper for the Springfield JV Project
Details of all relevant intersections at the Springfield JV Project received by Talisman are provided below. Estimated true widths have been calculated using estimated dip and dip-direction of modelled mineralisation surfaces at the drill-hole intersection and azimuth and dip of the drill-hole.
Calculation of relevance for inclusion into this table is based on a 0.5%Cu cut-off, no more than 3m of internal dilution and a minimum composite grade of 1%Cu. Intersection length, Cu (%), Au (ppm), Ag (ppm) and Zn (%) are rounded to 1 decimal point.

Appendix 1: JORC Table 1
Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down-hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
•The sampling method employed by Sandfire i s h a l f -core sampling of NQ2 core from diamond drilling (DD). •Sandfire collect RC samples by cone splitter for single metre samples or a sampling spear for first pass composite samples using a face sampling hammer with a nominal hole diameter of 140mm. •Sampling is guided by Sandfire protocols as per industry standard. •Diamond drill core sample size reduction is through a Jaques jaw crusher to -10mm and a second stage reduction via Boyd crusher to -4mm. Representative sub samples are split and pulverised via an LM5 mill. •RC samples are crushed to -4mm through a Boyd crusher and representative sub samples are split and pulverised with an LM5 mill. •Pulverising is to nominal 90% passing -75µm and is checked using wet sieving technique. •Samples are assayed using Mixed 4 Acid Digest (MAD) 0.3g charge and MAD Hotbox 0.15g charge methods with ICPOES or ICPMS. •Fire Assay is completed by firing 40g portion of the sample with ICPMS finish. |
| Drilling techniques |
• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
• Diamond drilling is completed using NQ2 size coring equipment. • RC drilling is with a face sampling hammer of a nominal 140mm hole diameter. •All core, where possible is oriented using a Reflex ACT II RD orientation tool. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and |
•Diamond core recovery is logged and captured into the database. Core recoveries are measured by drillers for every drill run. The core length recovered is physically measured for each run and recorded and used to calculate the core recovery as a percentage of core recovered. •Appropriate measures are taken to maximise sample recovery and ensure the representative nature of the samples. This includes diamond core |

being reconstructed into continuous intervals on angle iron racks for orientation, metre marking and reconciled against core block markers. •RC sample recovery is good with almost no wet sampling in the project area. •Samples are routinely weighed and the information captured into the central secured database. •No sample recovery issues have impacted on potential sample bias. |
|
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. • The total length and percentage of the relevant intersections logged. |
•Geological logging is completed for all holes and is representative across the orebody. The lithology, alteration and structural characteristics of core are logged directly to a digital format following procedures, and using Sandfire NL geologic codes. Data is imported into Sandfire NL’s central database after validation in LogChief™. •Logging is both qualitative and quantitative depending on field being logged. •All cores are photographed. •All drill holes are fully logged. |
| Sub- sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• Diamond core orientations are completed where possible and all core is marked prior to sampling. Half core samples are produced using an Almonte Core Saw. Samples are weighed and recorded. •RC samples are split using a cone or riffle splitter. The majority of samples collected are dry. On occasion that wet samples are encountered they are dried prior to splitting with a riffle splitter. •All samples are sorted, dried at 80° for up to 24 hours and weighed. Samples are then crushed through a Jaques crusher to nominal -10mm. A second stage crushing is through a Boyd crusher to nominal -4mm. •Sample splits are weighed at a frequency of 1:20 and entered into the job results file. Pulverising is completed using LM5 mill to 90% passing 75%µm using wet sieving technique. •1:20 grind quality checks are completed for 90% passing 75%µm criteria to ensure representativeness of sub-samples. •Sampling is carried out in accordance with Sandfire protocols as per industry best practice. •No field duplicates have been taken. •The sample sizes are considered appropriate for VHMS andgold mineralisation types. |

• The Doolgunna project lies within the Proterozoic- aged Bryah rift basin enclosed between the Archaean Marymia Inlier to the north and the Proterozoic Yerrida basin to the south. • The principal exploration targets at the Doolgunna Projects are Volcanogenic Massive Sulphide (VMS) deposits located with the Proterozoic Bryah Basin of Western Australia. |
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill holecollar |
• Refer to Table 1 of this document – Drillhole Information Summary, Doolgunna JV Project. |

| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Significant intersections are based on greater than 0.5% Cu and may include up to a maximum of 3.0m of internal dilution, with a minimum composite grade of 1.0% Cu. • Cu grades used for calculating significant intersections are uncut. • Minimum and maximum diamond core sample intervals used for intersection calculation are 0.3m and 1.2m respectively subject to location of geological boundaries. • Reported intersections from RC drilling are based on regular 1 metre sample intervals. • No metal equivalents are used in the intersection calculation. • Where core loss occurs; the average length- weighted grade of the two adjacent samples are attributed to the interval for the purpose of calculating the intersection. The maximum interval of missing core which can be incorporated with the reported intersection is 1m. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill-hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
• All drill-hole intercepts in this release are reported as both down-hole intersection widths and estimated true width intersections (refer Table 2: Drill hole assay intersections >1% for the Doolgunna JV Project). • The geometry of the mineralisation has been interpreted using top of mineralisation surfaces that link mineralised zones, thought to be continuous, between neighbouring drillholes. Given the variable, and often steeply dipping orientation of the mineralisation, the angle between mineralisation and drillholes is not consistent. Downhole intercepts for each drillhole are converted to estimated true widths using a trigonometric function that utilises the dip and dip direction of the interpreted top of mineralisation surface(at the intersectionpoint of that drillhole) |

| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Appropriate maps with scale are included within the body of the accompanying document. |
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• The accompanying document is considered to represent a balanced report. •Reporting of grades is done in a consistent manner. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Other exploration data collected is not considered as material to this document at this stage. Further data collection will be reviewed and reported when considered material. |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step- out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• Drilling is continuing at Monty. •Other drilling planned across the Springfield JV project includes reconnaissance and exploration drilling with diamond, RC and AC drilling techniques. |
